Google Cloud has announced an open and programmable global cloud networking platform, Cross-Cloud Network.

A mixture of new and existing tech from both Google and partners, the Cross-Cloud Network service is aimed at helping enterprises operate across multiple clouds.

The service is built around Cross-Cloud Interconnect, originally released in May, which offers a managed interconnect with 10 Gbps or 100 Gbps bandwidth, backed with a 99.99 percent SLA. It supports Alibaba Cloud, Amazon Web Services, Microsoft Azure, and Oracle Cloud Infrastructure, and is available in all of Google Cloud's regions.

“Yahoo Mail is moving its backend onto Google Cloud and leveraging the planet-scale network for high performance and secure access to Google's data services," Aaron Lake, SVP and CIO at Yahoo, said.

"Cross-Cloud Network and Interconnects for high-scaled and high-performing secure access to Spanner and BigQuery will help Yahoo deliver performance and security across hundreds of millions of mailboxes."

Google is also partnering with companies like BT to integrate its network with their global fabrics. "BT is pleased to partner with Google Cloud in enabling customers to connect to the Google Cloud's Cross-Cloud Network using the BT Global Fabric," Colin Bannon, CTO of BT Global Services, said.

"Google's global WAN and BT’s network are interconnected globally to enable enterprise branches and users to connect to cloud-based applications with the highest reliability and performance."
